To ell wllom t may concern:

.lie itiaknoivn that We, SAMUEL EDWARD Anni' and JAY il. HERN, citizensol' 'the United States, residing at Fellows, in the county of Kern,State of California, have invented a nei* and useful Elevatorq of whichthe following is a specilication.

rlhe present invention appertains to elevators for raising sucker,puinoor polish rods from drilled Wells, and aims to provide a novel andirrprovcd device of that character.

The present device has novel means for attaching it to the sucker rod orother ele* ment to be lifted, whereby the elevator is not liable to bedetached accidentally. although it can be removed easily by hand fromthe rod.

It is also Within the scope of the invcntion to pro-vide an elevatorofthe nature indicated which is extremely'sinq'lle, com-- pact and.inexpensive in construction, and which is thoroughly practical, reliableand eiiicient in use.

With the foregoing and other objectsin view which will appear as thec'lescription proceeds, he invention residesjin theecomhination andarrangement cliparts and in the details of construction hereinafterclescrihecl and claimed, it being understood that changes in the precise'nhodiment of the invention herein disclosed'oan be made with-in.thescope of what is claimed Without departing from the spirit of theinvention.

The invention isV illustrated in the" accompanying drawing,Wlicieinz-Figiix'e l lis a plan view of the elevator, portions beingbroken away. Fig. 2 is a section taken on the line 2-2 ol" Fig. l.

In carrying ont the invention, there is provided a body 1 provided 2adapted to be journaled in the terminals ci? 'an ordinary elevator hail(not shown); and said body is also provided with a radial open slot 3for the reception of the sucker rod or other member which is to beelevated withv the body 1. Thebocly l is formed at opposite sides of theslot 3 with recesses "4l extending from the open end or menthol' theslot 3 to a point short ot' the inner end of said slot and locatedbetween the upper and lower faces-of the body. The recesses 4 providewalls facing the slot 3 and are provided with extensions 5 at theirouter ends projecting away from one another `to `latches 7 are providedwith c other so as to enter at fliainetrically opposite points withoutstanding trunnions those sides of the body from which the trunnions 2project and providing Walls at an angle with the aforesaid 'Walls Thebody l also has sockets or cavities 6 openM imr into the recesses ladjacent their .innerl ends.

Mounted for swinging movements Within the recesses 4 are. latches ,7,which are pivotally mounted upon bolts 8 or other pivot elements engagedthrough the body 1 at the opposite sides of and adjacent to the open endof the slot and extending through the recesses Il between their ends.The latches Z project inwardly and converge toward. one another7 theinner ends of the latches being' adapted to abut against the rod whichfits within the slot 3 adjacent the inner end thereof. The outer ends ofthe linger pieces 9 adjacent to the open end of the slot 3' eX- tenclingat obtuse angles from the latches 7 in opposite directions away fronroneanthe extensions 5 of the recesses,

The latches 7 are normally swung toward one. another within the slot 3underr the inlin ence of coiledswire expansion spriz-igs confinedbetween the body l and latches, saith springs l0 seating in the sockets6 and Within sockets ll with which the latches are provided.

To apply the elevator to the sucker roel, the body l is movedtransversely so that the rod enters the slot 3. and the rod. can readilymove -pas't thelatches 7 which are forced apart into the recesses 4fbythe rod. After the rod moves to thc'inner end of the/slot 3 past thelatches' the latches will be swung behind the rod under the influence ofthe springs l0.y thus holding the elevator in place upon the rod. li therod and elevator rotatey 'relative to one another, this is notl apt torellcasethe latches, since the tendency of the rod in rotating againstthe latches to move one latch into' its recess tends to move the otherlatch ont of its recess. Consequently, the latches cannot both beaccidentally -lorced `l aclc-into their recesses. When the elevator isapplied to the roel, so that the rod will he raised. with the elevator,the elevator can he raised in the ordinary ina-nner to carry the rodupwardly therewith." It .is an easy matter to remove the elevator fromhe rod, since the linger pieces 9 een be pressed toward one another bythe thumb and one nger of the hand, which will swingY the latches 7 awayfrom .one another, whereby the body l can be moi'ed sidewiSe to removeit from the rod without interference. The extensions 5 of the recesses l:wconinuidate the thumb and lingers` and this Jfacilitutes theretraction of the latches from the slot 3 in \\'ithdrawing the elevatorfrom the rod.

The. present elevator is extremely simple in construction, is not apt toget out of order, und 'ulils its oiiice in a thoroughly reliable andetlicacious manner.

lt is preferable to provide the bod) l with apertures 12 extending; tothe faces of the bod)y troni the corners of the recesses 4, whereby sandand other extraneous matter which accumulates within said recesses fanbe washed out or discharged through said apertures. c

Havine; thus described the invention, what is claimed as new is: y

An elevator embodying,r a body baviner radial open slot and recesses atthe opposite sides of said slot between the faces of the body extendingfrom the open end oi' the slot to a point short of the inner end of theslot, said recesses providing walls hiring the. slot, said recesseshaving extensions projecting away from one another at. the open end ofthe slot for receiving the thumb and finger of a hand for movementtoward one another, -said extensions providing walls arranged at. anangle with the aforesaid walls, pivot members carried by the body withinsaid rocesses between the ends thereof, latches pivotally mounted uponsaid pivot members within said recesses and projecting toward the closedend of the slot, said latches having linger pieces extendiugg` at obtuseangles therefrom beyond the pivot members and projecting away from oneanother to Contact with the second nientioned walls, and ex pansionsprings between the latches and first mentioned walls; for swinging thelatches toward one :mother and moving the linger pieces against thesecond mentioned Walls.

ln tcstiinon)v that we claim the. foregoing as' our own. we have heretoailixed our natures in the presence of two uitnesses.
